Java Bridge Server not working after JDK upgrade

[sroback_splunk]

Hi.

We updated JDK on our Red Hat servers from version 1.6 to 1.7. Now our DB Connect App shows the Java Bridge Server is not running. And the dbx.log contains the following error messages:

2014-05-02 10:30:05.286 dbx6162:ERROR:TailDatabaseMonitor - Error while executing database monitor: com.splunk.dbx.DbxException: Error getting database connection: Pool not open

Anyone know what might be causing this? Recommendations for a fix? Thanks!

This error occurs when the JDK version referenced in the path to JAVA_HOME inside the DB Connect app does not match the JDK version installed on the server. dbx.log will show an "Error_getting_database_connection:_Pool_not_open" message. The resolution for this issue can be found in the troubleshooting section of the DB Connect app docs.
